There have long been threads of investigation into covert channels, and threads of investigation into anonymity, but these two closely related areas of information hiding have not been directly associated. This paper represents an initial inquiry into the relationship between covert channel capacity and anonymity, and poses more questions than it answers.(More)
The Fox-Wright Psi function is a special case of Fox's H-function and a generalization of the generalized hypergeometric function. In the present paper we show that the Psi function reduces to a single generalized hypergeometric function when certain of its parameters are integers and to a nite sum of generalized hypergeometric functions when these(More)
OBJECTIVES Cohen's kappa coefficient is presently a standard tool for the analysis of agreement on a binary outcome between two tests. In view of the ubiquity of the use of sensitivity, specificity, raw agreement and kappa in clinical studies, clearly it is advantageous to have a useful analytic relation connecting these measures of agreement. METHODS We(More)
We deduce an explicit representation for the coefficients in a finite expansion of a certain class of generalized hypergeometric functions that contain multiple pairs of numeratorial and denominatorial parameters differing by positive integers. The expansion alluded to is given in terms of these coefficients and hypergeometric functions of lower order.(More)
Prediction of life tables, which provide the most empirical information available about the statistical properties of aging, provides a rigorous test for any theory of aging as manifested at the organismic level of biological organization. For this purpose, a set of test tables for the wild boar (Sus scrofa), domestic sheep (Ovis aries), Dall sheep (Ovis(More)
